It seems Nicole Richie fired her stylist a little too late ... she just landed at the top of PETA's Annual Worst-Dressed List.

The animal rights group showed no mercy as they dug their their claws into fur-loving Richie by saying, "This pelt-wearing party girl is all animal skin and bones. She's an incredible shrinking woman with the heart to match." Meow!

PETA put Hollywood wonder twin Ashley Olsen in the #2 spot: "Wearing fur does add 20 pounds, but if Ashley wants to fill out her frame, we suggest using a fork instead." Ouch!

Christina Ricci landed at #3 for posing on a magazine cover wearing "fur from slaughtered reindeer." Fur-galicious Eva Longoria was named #4 because they wish "She'd be more sympathetic to the plight of rabbits, considering the way she screws around like one on Wisteria Lane." Well!
